So to be honest, you realized you were talking out of your ass after you googled some shit from weeks ago and decided to nitpick a post. Good for you man, you are smarter today than when you made your initial idiotic statement.
In case you are wondering, I had to know every muscle/tendon/ligaments origin, insertion, nerve intervention and action just to practice my chosen field. So yes, I do understand you can remove vertebrae and still function, you can remove legs and arms and still function also, this doesn't mean there isn't a function for arms and legs. People survive and function after having a frontal lobe removed, that doesn't mean it's part of the human body that isn't necessary. (Unless of course you are a fiscal liberal, then no, you don't need a frontal lobe)
Your ego wouldn't let it go that you got called out on your stupidity and decided everyone needed a reminder? OK then....
Go back and read your original claim and think if it's a good idea for you to remind everyone of what you were trying to argue.
